HEEL-BURNIsHiNe MACHINE.

SPECIFICATION forming part of Letters Patent No. 248,965, dated November 1, 1881.

Application filed July To all whom vit may concern:

Be it known that I, MERRILL A. TYLER, of Rockland,in the county of Plymouth and State of Massachusetts, have invented certain Improvements in Heel-Burnishing Machines, ot' which the following is a specification.

This invention relates to a heel-burnishing machine having a reciprocating burnishingtool and ajacl; to support the heel while it is beingburnished; andlthasforitsobjcct mainly to enable the operator to so control the position of the tool that he can accommodate it to varying inclinations in the same heel and to different inclinations in different heels, and can cause the tool to act on either theupper or the lower edge otl the heel without acting on the other edge.

The invention also has for its object to provide certain improvements relating to the tool and the means for supporting and operating.

the same.

To theseends my invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming part of this speciticatiou,Figure 1 represents a side elevationofalieel-burnishingmacliinecinbodying myinvention. Fig.2 represents a rear elevation ot' the same. Fig. 3 represents an elevation ot' the opposite sideot` a part ot' themachille. Fig. 4 represents a section on linear x, Fig. 1. Fig. 5 represents an enlarged side elevation of the bi'irnishing-tool and its supporting mechanism. Fig. 6 represents a top view of same. Fig. 7 represents a similar view,\vith a part of the standard broken away and. the tool in a different position. Fig. S represents a section on line y gf, Fig. 6.

The saine letters relate to the saine parts in all the figures.

In the drawings, J represents the jack on which the heel H is held during the burnishing operation, said jack being of any suitable construction, and adapted to be rotated by hand or power. A preferred form ot' jack is shown in my Patent No. 247,714, dated September 27, 1881.

a represents the burnishing-tool, and b represents the reciprocating or oscillating carriage supporting and moving the tool. The carriage is pivoted at c c toa standard, d, and

is oscillated on its pivots to give the tool an upward and downward motion by mechanism hereinafter described. The tool a is attached directly to a stock or plate, a', which is movable laterally upon the carriage b, in a plane substantially at right angles to the reciprocating movement of said carriage. The stock-a is guided so that its lateral movement will be a swinging motion, as on a pivot, and to this end the stock is preferably pivoted to the carriage at c, although, if desired, the pivot may be omitted and the stock guided by means of its quadrantshaped back bearing against a correspondingly-shaped wall on the carriage, the stock being prevented from being raised from the carriage by an overhanging plate or iiange,f. This lateral movability of the stock and tool upon the carriage enables the operator to control the position or inclination ofthe tool with relation to the axis upon which the heel rotates, so that he can accommodate the tool to different degrees of inclination in the same heel, as when the rear portion is inclined more lthan the sides, and to different inclinations in different heels, and can also cause the tool to bear upon one portion of the heelsay at the upper edgewithout bearing upon the other, so that such portion of the heel can receive more of the action of the burnisliing-tool than other portions. The stock is provided with a handle, t', pivoted at i to an arm fixed to the stock a', and adapted to be grasped by the operator, the pivoted point of the handle being preferably in line with the pivots o c of the carriage when the stock is in the position shown iu Fig. 6, so that the handle will receive as littlc as possible ot' the reciprocating motion ot' the carriage. The operating face ot' the tool a is preferably curved in the arc oi' a circle whose center is the pivotal point of the carriage. This form ofthe tool prevents the tool from pounding on the heel in its vibrating motion. The tool is preferably provided with a cavity, le, into which a heatingiiame may be introduced when the tool is made of metal. It' desired, however, the tool may be made of stone, and secured to the stock a by suitable clamps. y

Zrepresents a guard attached to the standard d, and projecting over the burnishing-face ot' the tool a, and provided with a lip, l', adapted to bear upon the rand of the heel being burnished. Thisguard l,being.interposcd between the burnishing-tool and the ripper of the boot or shoe, prevents the latter from being rubbed by the tool, and being non-reciprocating, by reason of its attachment to the standard d, does not rub or burnish the upper nor the upper edge of the rand.

m represents an arm pivoted to the stock a', and projecting through a slot in the tool a, the projecting end of said arm forming a lip, l2, adapted to bear upon the bottom ot' the heel while the tool a is bearing upon the edge of the heel. The lip l2 reciprocates with the tool and burnishes the margin of the bottom surface, preventing the formation of a burr on the bottom of the heel by the action ot' the tool a. The lip l2 is given a yielding movement by means of' a spring, a, which draws the lip against the bottom of the heel and enables it to conform to the height of the heel. The guard l, which is at the same time iu contact with the top of the heel, may have a yielding movement, or may be rigidly attached to the standard d. The sides of the slot in the tool a, through which the lip l2 projects, are rounded at their junction with the operating-face of the tool to avoid the formation of angles on the operating-face.

The carriage b is oseillated on its pivots to reciprocate the tool by means of the Iollowing elements, viz: a pulley, 0, journaled on the standard d, and provided with a cam-groove, p; a slide, r, adapted to move in a slot or guide in the standard and provided with a stud, s, entering said groove; an arm, t, rigidly attached to the carriage b; and a link, u, connecting the slide 1' to the arm t. The rotation of the pulley o causes the cam-groove b to reoiprocate the slide r, the latter, lhrough the link u, oscillating the carriage b. The pulley ois belted to a pulley, on a shaft, o, the latter being driven from another shaft and driving the pulley 0. The standard d is pivotcd to the rigid bearings w w, in which the shaft c is pivoted, and is adapted to swing and carry the tool a toward and from the jack. The stainlard is preferablyarranged to gravitate toward the jack when in operative position, and thereby press the tool a againstth e heel. Ihe standard may be forced toward the jack to impart additional pressure to the tool by any suitable means.

The jack J is preferably adapted to move endwise in its fixed supports jj sufficiently to enable the heel to be moved crosswise of the tool whileit is being burnished, so that in case the heel is too high for the width of the tool it can be moved to present all parts of its surface to the tool. A

My machine being constructed as above described, its operation is as follows: The shoe having been secured in the jack as in my patent referred to, and rotary motion having been applied to the shaft c, the cam-pulley o is rotated, and by its groove imparts a verticallyreciprocating motion to the tool through the connecting mechanism specified. The tool is moved into position against the heel by the controlling-lever @',which also governs its angle of present action to the heel, and the heel is moved through the required are in the jack to permit the tool to impart throughout its edge the required conformation, the tool being mounted upon a movable frame, and being indepen den tly adjustable vertically and laterally it can be adapted to any character of heel.

Having thus described my invention, I claiml. The carriage b, a support upon which said carriage is pivoted to move in a vertical plane, and means to oscillate said carriage upon its pivot, combined with the tool-stock a', arranged upon such carriage and adapted to receive motion in a plane substantially at right angles to the plane of movement of the carriage, and the handle i to operate said stock, all substantially as shown and described.

2. In a burnisher, the oscillating carriage b, and the tool-stock a', carrying the tool a and movable in a plane at right angles to the plane ot' movement of the carriage, combined with the support d, and the guard l, arranged thereupon, substantially as and for the purpose described.

3. The combination, with the reciprocating burnishing-tool, of a movable lip, l2, reciprocating with the tool and a spring adapted to press said lip against the marginal portion of the tread ot' the heel, said lip rubbing the tread and preventing the formation of a burr by the action of the burnishing-tool, as set forth.

4. The combination ofthe support d, the reciprocating burnishing-tool a, the non-reciprocating guard secured to the support and adapted to bear upon the rand, and the reciprocating lip adapted to bear upon the bottom of the heel, as set forth.

5. The burnishing tool a, constructed as shown and described, combined with an adjustable stock upon which it is mounted, and a pivotal carriage in which the stoel: is arranged, substantially as shown and described.

6. The combination of the pivotcd arm or support d, the pulley o, journaled in said arm and provided with the cam-groovep, the slide 1', reeiprocated by said groove in a slot in the arm d, the tool-supporting carriage b, pivoted to the arm d, and provided with the arm t, and the link u, connecting the arm t with the slide 9', all arranged and operating substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 16th day of July, A. D. 1881.
